Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.
[0021] Such as figure 1 Shown is a logic principle diagram of a vehicle rutting optimization system of the present invention, including a perception system 1 , an intelligent driving system 2 , a driving control system 3 and a suspension system 4 .
[0022] The above perception system 1 includes a video camera, radar sensor, laser range finder, light compensation source, perception fusion, etc., which can provide information such as driving route planning and scene driving plan, and can also provide the calculation of the rutted road surface curve that the vehicle will travel , and send the rutted road surface curve to the intelligent driving system 2. Specifically, the above-mentioned driving route planning includes information such as the current position of the vehicle obtained through the navigation system, the optimal driving route that ...

The invention provides a vehicle running track optimization system which comprises a sensing system, an intelligent driving system, a driving control system and a suspension system, the sensing systemcan send a rut road surface curve that a vehicle is going to pass to the intelligent driving system. The intelligent driving system can optimize vehicle driving ruts according to a driving route planand a scene driving plan and send an optimization result to the driving control system and the suspension system. And the driving control system and the suspension system can execute an optimal vehicle driving track plan, the passing speed of each point of the curve and a suspension system control strategy of each point of the curve and feed back the optimal vehicle driving track plan, the passing speed and the suspension system control strategy to the intelligent driving system. The invention further provides an optimization method of the vehicle running track. The optimal rut running routeand running state of the vehicle running along the rut road surface can be ensured, the running comfort and safety of the vehicle can be improved, and the service life of the vehicle can be prolonged.
Description
technical field [0001] The invention relates to the technical field of automatic driving vehicles, in particular to a vehicle rutting optimization system and a method thereof. Background technique [0002] Autonomous vehicles, also known as unmanned vehicles, are intelligent vehicles composed of advanced assisted driving technologies. Autonomous driving technology mainly includes perception, map navigation, driving planning, operation decision-making, driving execution and other directions. The driving planning is identified by the perception system including video cameras, radar sensors, laser range finders, and light compensation sources. Vehicles, pedestrians, obstacles and other information for planning and operations such as lane selection, obstacle avoidance, overtaking and yielding. [0003] For example, in the description of the Chinese invention patent CN 201711034376.4, a method and device for controlling the automatic driving of a tourist bus are disclosed, inclu...
